# Use sunnypilot in a car

## What You Need

1. **A supported vehicle** — Check the compatibility list for your car's make, model, and year
2. **A comma device** — comma 3X or compatible hardware
3. **A vehicle harness** — Connects the device to your car's systems
4. **An internet connection** — For initial setup and software updates

## Getting Started

1. Mount the device on your windshield
2. Connect the harness to your car
3. Install sunnypilot using one of the setup methods:
    - [URL Method](../setup/url-method.md) — Easiest, recommended for most users
    - [SSH Method](../setup/ssh-method.md) — For advanced users

## First Drive

After installation:

1. Power on the device
2. Wait for the system to calibrate (drive straight for a few minutes)
3. Enable cruise control as you normally would
4. The system will begin assisting with steering and speed control

!!! tip
    Give the system time to calibrate. Steering assistance improves after the first few minutes of straight driving.

sunnypilot offers many configurable options. Access settings through the on-device interface:

- **Cruise Control** — Speed management, gap settings, and cruise behavior
- **Steering** — Lane keeping, MADS, and steering tuning
- **Display & Visuals** — Customize the on-screen display

See the [Settings Reference](../settings/cruise/index.md) for a complete guide to all options.
